Foremost, I think the runtime should have been around 45 minutes to properly impact the viewers. 23-24 minutes episodes aren't ideal when you're dealing with such delicate societal topics. Makers should have given viewers the time to settle in and connect themselves. I would recommend waiting for 3-4 episodes and then start watching.
Now, let's come to the societal issue this drama will be dealing with, this is not a BL, it's an LGBTQ drama, so please keep that in mind when jumping in. You gotta bring your compassion along with your passion while watching.
In the first episode, there's a disclaimer in the beginning which viewers should read carefully. Though the drama is set up of 1990s, the society is still very much prejudiced and harsh against a 'girly' boy than it is against a 'boyish' girl. If I am to give an example from my own experiences, we had a boy in our school, who liked 'girly' stuffs were harassed/made fun of by other boys and even some girls. But a tomboy was quite famous among boys and even girls. She played volleyball in district level for our school.
Nevertheless, I am through and through impressed by Araki Towa, he's going to win awards for his protreyal of Mishima for sure
